An early Cleveland-style rigid archbar truck with inside brakes for close clearances. 55" wheelbase, similar to what the Pennsylvania used in the 1870s-90s. Requires 33" wheelsets with .540" (13.70mm) length axles (MTL low or new standard profile, FVM, etc). Mounts with a screw up to #1-72, recess provided for the head. Clean with alcohol before painting with acrylics (recommended). Part T71s. Because of very thin details be sure to mark the "print it anyway" box at checkout, or get the robust T71rs version that has thicker archbars and will print regardless.
